Specification of Letters Patent.

Patented Uct.1, me.

Application filed September 20, 1917. Serial No. 192,331.

To all whom it may concern:

Be it known that I, HENRY STOFFEL, a citizen of the United States, residing at Tulsa, in the county of Tulsa and State of Oklahoma, have invented a new and useful the following is a specification.

' The-present invention appertains to valves,

and relates to improvements in float con trolled valves.

It is the object of the invention to provide a novel operative connection between the float and valve member to operate the latter in an effective manner, and permit of adjustments being made to suit the various condi tions, the valve member being unseated against the fluid pressure and seating automatically as a check valve should the operating mechanism become broken or injured.

Another object is the provision of novel means for adjustingthe opening of the valve by the operating mechanism.

A further object of the invention is the provision of a novel connection between the fluid supply pipe and valve casing, permitting, of the ready attachment and separation thereof.

A still further object of the invention is the provision of novel means for supporting the valve casing from the upstanding fluid supply pipe and permitting the valve casing to be oifset or adjusted toward either i side which isespecially desirable in a flushing tank to avoid interference with the plungel orflushing device.

With the foregoing and other objects in view, which will appear as the description proceeds, the-invention resides in the com in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodimentof the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustratedin the accoman in drawin wherein:

Figure "1 is aside elevation of the valve structure, portions beingshown in section.

Figs. 2 and 3 are sectional details on the l' respective lines 22 and 3-3 of Fig. 1.

ported by a cup-shaped tail piece or member 2 having an end Wall 2*, and having an outstanding flange 3 at its open end abutting against one end of the casing 1 and fastened to the casing by means of a union 4 threaded thereon and having an inturned flange or lip overlapping the flange 3. The tail piece 2 is provided near its closed end with an internal sleeve integral with the end wall 2 and with one side of the member 2, the sleeve being threaded onto the upper end portion 6 of an upstanding water or fluid supply pipe 7 the lower end of whichis threaded or otherwise engaged into a sleeve 8 to ex tend through the bottom of the tank. The

sleeve 8 has an upper flange or nut 9 to seat on the bottom of the tank, and a binding nut 10 is threadedon the sleeve to bear upwardly against the bottom of the tankfor firmly supporting the pipe7 and preventing-leakage. The sleeve 8 also serves as a couplingfor attaching the pipe leading to the source of can slide back onto the tail piece 2.

That end of the casing 1 which is secured to the tail piece 2 has apartition or diaphragm 11 with a central inlet .12 and a surrounding rib 13 forming a valve seat projecting outwardly from the valve casing into thetail piece 2. The casing 1 is further provided with a lateral outlet 14:, lowermost as illustrated, and into which an outlet tube or nozzle 15 is threaded or otherwise secured. The tube 15 can extend to a point near the bottom of the tank to render the inflow of water as noiseless as possible.

The casing 1 has a tubular extension or cylinder 16 at that end opposite to the end or partition 11, and a plunger or piston 17 is slidable in the extension 16 toward and away from the inlet 12. A valve stem 18 away from the valve seat, the valve head moves toward said seat, the valve head being seatable in the direction of flow from the pipe 7 into the casing 1, therefore, acting as a check valve when free to do so. Thus, should the actuating mechanism become broken Seated by the fluid pressure to avoid waste offluid, overflow thereof, or the like.- When the valve member or head is unseated, thefluid in flowing into the casing will also exert a pressure against the plunger of piston 17, tending to move it away from the valve seat to seat the valve head.

The actuating mechanism for the valve 1 head embodies a lever 23 projecting laterally or upwardly through longitudinal slots 24 in diametrically opposite sides of theextension or cylinder 16 near the free end thereof, the lower end of said lever being pivoted, as at 25, to depending ears 26 projecting from the extension 16 at opposite sides of its lowermost slot 24. The lever 23' projects upwardly through a diametrical slot 27 provided in the plunger 17, and the lever has'a rounded portion 28 between its ends working within the slot 27 to slide the plunger back and forth when the lever is oscillated. The lever 23 is, in turn, operated by the lever 29 pivoted between its ends, as at 30, to an upstanding overhanging bracket 31 carried by the top of the casing 1 and projecting over the extension 16. The lower arm of the lever 29 is connected by a link 32 with the upper end of the lever 23, and the lever 29 is operated by a float and weight, as will presently appear.

The upper arm of the lever 29 has a circular jaw 33 at one side of which is disposed a circular jaw or disk 34, said jaws having interengageable radial teeth 35 for the rotary adjustment of the jaw 34, and an eye bolt 36 or other pivot extends through central openings or apertures in said jaws, a nut 37 being threaded on the bolt and bearing against the jaw 33 opposite to the jaw 34. A rod 38 of suitable length extends through the eye of the bolt 36 and is seatable within a diametri'cal groove 39 with which the jaw 34 is provided at that sideopposite to the jaw 33. Thus,- when the nut 37 is tightened, the rod 38 is drawn tightly into the groove 39, and the jaws 33 and 34 are clamped together by the or injured, the valve head will be same operation. When the nut 37 is loosened, this permits the rod 38 to be slid longitudi nally in the groove 39, and said rod can be adjusted angularly relatively to the lever 29 by swinging said rod so that the jaw 34 turns with it. Then, when the nut 37 is again tightened, the parts are clamped in their newly adjusted position, thus permitting the rod 38 to be placed at different angles relatively to the lever 29 and ermittingsaid rod to be adjusted to hung the float 40 at the end thereof near to or farther from said lever, to change the leverage. The float 40 may be of any suitable construction, preferably of the hollow type, and also serve as a weight to depress the rod 38 and swing the lever 29 accordingly when-"the water level is lowered. When the water level rises, the float 40 in being buoyed up, will swing the lever 29 counter clockwise, as seen in Fig. 1, so'that the link 32 will swing the lever 23 toward the right, thereby mov ing the plunger 17 in the same direction, and moving the valve head toward its seat, assisted by the water pressure. The flow of water is, therefore, shut ofl as soon as the water level reaches the predetermined.

rod 38, where y the weight will assure of the gravitation of the rod 39. This weight 41 is slidable or adjustable on the rod 38, being held in any adjusted position by means of a set screw 42 or its equivalent The weight 41 can, therefore, beset at the proper position, so as not to prevent the upward movement of the float 40 by the rise in water level, but to assure of the unseating of the valve head or member against the water pressure when the water level is lowered. Thus, when the water level, is lowered,the combined weight of the float 40 and weight 41 must be suflicient to swing the rod 39 downwardly with enough leverage to unseat the valve head, the rod-38 swlnging the lever 29 clockwise whereby to move the lever 23 and plunger 17 toward the left to move the valve headlikewise against waterpressurer The adjustment of the weight 41 enables the device to be set to operate smoothly and efliciently, but in some cases, if the float 40 is heavy enough,

the weight 41 need notbe used. Its preswith the end wall and with one side of the tail-piece and having its axis disposed approxlmately at right angles to the axis of the tall-piece; a pipe received in the sleeve;
